I have not earned anything from August, last earning was when I sold some BTC, although it was earned in April. The only way to survive in this situation is to wait for good days to come. Mining is very expensive now a days. It was profitable till june 2017. Due to increase in prices miners, graphic cards and other stuff like electricity.
I guess most of us didn't earn enough in August since it was the start of the bear market and most campaigns are gone since then. And most traders that were holding some of their investments tend to sell most of their coins on their portfolio. To think that the market would bounce back but they were wrong but instead, the market keeps on going down and the worst when this month Bitcoin dropped to almost $2k.
